I was looking through my installed snaps, and realised that I no longer needed anbox or canonical-livepatch installed, so I decided to remove them:
$ snap remove anbox canonical-livepatch

anbox removed
canonical-livepatch removed
These conflicting change messages are output at seemingly arbitrary points during the 50 seconds that this command took to run, without any explanation interleaved. Given that everything eventually succeeded, are these messages that an end user actually needs to see?
